RAILWAY-TRICYCLE;

Error -marrow forming part of Letters Patent No. 354,318, dated December14. L886.

Applicnlioriflled July .36, 1886. Serial No. 209,114. No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM HAYES, of Los Angeles, in the county of LosAngeles and State of California, have invented a new and ImprovedRailway-Tricycle, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improvedrailway-tricycle, in which the friction of the flanges of thewheelsagainst the'rails on curves as well as on straight tracks is avoided.

The invention consists of a trailingwheel which is free to swing withincertain limits, and is without flanges, and of a seat placed at rightangles to the main wheels.

The invention also consists of various parts and details andcombinations of the same, as will be fully described hereinaftenand thenpointed out in the claims.

Reference is to be had tothe accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of myimprovement. Fig. 2 is a side elevation ofthe same. Fig. 3 is a sectional plan view of the same on the line a: :0of Fig. 2. Fig. 4 is a vertical cross section of the trailingwheel onthe line 3 1 Fig. 1, and Fig. 5 is a sectional elevation of part of theframe on the line z z of Fig. 1.

Heretofore railway trieycles and railway hand-cars depended on theflanges of their wheels to act as guides on the track, and the flangesnecessarily rubbed against the rails, thereby causing considerablefriction.

In my improved tricycle I provide the main driving-wheels with lightflanges andincrease the tread, but preserve the inside wheel-gage, and Imakethe follower or trailing wheel without flanges and free to swingwithin certain limits, so as to permit the main wheels to governthemselves in the track and prevent friction of the flanges on therails.

The main wheels A, constructed as above described, are attached to themain axle B, which rotates in suitable bearings secured to the mainframe 0, from which extends a frame, D, sup ported at its outer end bythe follower or trailing wheel F, constructed as above described. Theframes 0 and D are strengthened by a brace, E.

The follower or trailing wheel F is attached tached, directly above theaxle G of the trailing-wheel F, a keeper, J, to each of which keepers ispivoted an arm, K, pivoted at its upper end to an eyebolt, L, turning inthe outer end of the frame D. Each armK is provided with an angular arm,K, which extends under a plate, M, secured to the under side of theframe D.

The seatN is fastened by suitable braces, O, to the main frame 0, and isplaced in such .a position that the rider faces at right angles to thetrack, instead of facing the air-current, whereby he presents lesssurface to the wind, and consequently reduces the resistance, and he isalso enabled to keep a lookout in both directions with equal facility.

It will be seen that the main wheels Ahave considerable play on therails P, whereby the frames 0 and D receive a vibratory motion when thetricycle is moving; but the follower or trailing wheel F is not affectedby this vibrating of the frames 0 and D, as the pivoted arm I, inconnection with the turning of the bolts L and the connecting-arms K,permits the trailing-wheel to remain in its assumed position on therails 1?, and it is not dragged across the rails by any vibrations ofthe frames 0 and D. It will also be seen that the trailing-wheel F willnot prevent the main wheels A from passing properly over a curve, as thetrailing-wheel is without flanges and is free to swing within certainlimits on the rails. It will be understood that as the trailing-wheel Fdoes not affect the main wheels A when passing over curves the flangesof the main wheels A cannot rub against the rails 1?. Thus any unduefriction is avoided.

In the drawings I do not show any means for propelling the tricycle, asany approved device for propulsion can be applied. I also do not confinemyself to any particular construction or combination of parts whichallow the frame and the entire body of the tricycle IOO the main wheelsprovided with flanges with a trailing-wheel having a cylindrical rim,snbstantially as shown and described.

2. In a railway-tricycle, the combination, with the main driving-wheels,each having a flange, of a trailing-wheel having a cylindrical rim andmounted on a pivoted frame, substantially as shown and described.

3. In a railway-tricycle, the main drivingwheels, each having a flangeand both being attached to an axle, and a frame on which the said axleis mounted, in combination with a trailingwheel, and an arm carryingsaid trailing-wheel and pivoted to the main frame, substantially asshown and described.

4. In a railway-tricycie, the main frame 0, the eXtension-framel), andthedriving-wheels A, each having a flange, and both mounted on the saidframe 0, in combination with thetrailing-wheel F, the pivoted forked armH, the arms K, and the eyebolts L, turning in the said frame D,snbstanti ally as shown and described.

' 5. In a railway-tricycle, the frames 0 and D and the plates M, incombination with the forked arm H,'pivoted to the main frame 0, thetrailingwheel F, mounted on the said arm H, the keepers J, attached tothe said arm H, the eyebolts L, turning in the frame D, and theconnecting-arms K, having the projections K, and each connecting aneyebolt, L, with a keeper,J,snbstantially as shown and described.
